You probably already know that Trinity and Guildhall are amalgamating. Why don't you go to one of their information sessions. They are holding one in London in June - I've booked a place...I believe that TrinityGuildhall are going to keep the option of specialist examiners ie a pianist examining a pianist etc although I think this will be limited to certain entry dates.I tend to agree with Steve's assessment and personally have always favoured the Guildhall Board. However when deciding on the Board I always consider the pupil's needs first and go for the syllabus I feel has the most attractive, rewarding pieces. The London College of Music also have some great ideas. I love their Leisure play syllabus. As Steve says Rock school material is great too.
